  A retroreflective sheet manufacturing method having the steps of placing a light-permeable protective film on glass beads in a support sheet which consists of a binder layer and a reinforcing layer, and which is provided with retroreflective glass beads buried in the binder layer, and thermally deforming parts of the support sheet under heating and pressure so as to partially bond the binder layer of the support sheet to the protective film, characterized in that the reinforcing layer of the support sheet consists of a cross-linked resin having shearing stress S in the range of 6x10⁶-1.2x10⁷ dyne/cm² before the thermal deformation of the support sheet has been carried out. A retroreflective sheet manufactured by this method has a high uniformity of the joint portions of the support sheet and protective film. Even when this retroflective sheet is used outdoors for a long period of time, troubles including the separation of the protective film do not substantially occur. This retroreflective sheet can be utilized extensively as a road sign board, a license plate for a vehicle, a sign board for construction work and an advertisement board.

  一种逆反射片材的制造方法，其步骤是在由粘合剂层和加强层组成的支撑片材中的玻璃珠上放置透光保护膜，在粘合剂层中埋有逆反射玻璃珠、在加热和加压条件下，使支撑片的部分热变形，从而将支撑片的粘结层部分粘合到保护膜上，其特征在于，支撑片的增强层由交联树脂组成，交联树脂的剪应力 S 在 6x10⁶-1.2x10⁷达因/平方厘米。用这种方法制造的逆反射膜在支撑膜和保护膜的连接部分具有很高的均匀性。即使在室外长期使用这种反光膜，也不会出现保护膜分离等问题。这种逆反射板可广泛用作道路标志牌、车辆牌照、建筑工程标志牌和广告牌。
